3 principle

The total particulate matter in the cigarette smoke was captured by a glass fiber filter, the benzo [α] pyrene in the total particulate was extracted with cyclohexane, and the extract was filtered through a solid phase Extraction column was used for the quantitative determination of benzo [α] pyrene by gas chromatography-mass spectrometry (GC-MS).

4 reagent

Note. Benzo [a] pyrene is a strong carcinogen. All pre-treatment operations should be carried out in a fume hood, the experimenter should wear protective gloves, Mask to ensure safety. After the collection of experimental waste to be unified treatment. Unless otherwise specified, analytical grade reagents should be used. The water should be distilled water or water of equivalent purity. 4.1 Cyclohexane.
